GlitterFever21 Posted September 26, 2022 Share Posted September 26, 2022 Hi! I am having an issue with the CPU cooler in my PC build. Whenever I boot my PC, the fans on the cooler run and it looks like the cooler is working. However, in my BIOS, the RPM shows 0 and the CPU (Intel i7-12700K) temperature rises. Is there anyone who is having the same issue and/or knows what I can do to fix it? Link to comment Share on other sites More sharing options...
c-attack Posted September 26, 2022 Share Posted September 26, 2022 Contact Corsair Support. The zero rpm and steadily rising temperature suggests the pump is not spinning. That’s not something you can accidentally do and the pump should always be spinning. Since the fans are spinning the Commander Core is getting power and that is also the source of the pump 12v supply. The only possible user fix is to power down the system, flip the PSU off, then disconnect the wide pump cable from the Commander Core. Reconnect it and make sure the white stripe is lined up with the matching mark on the Commander. PSU back on and power up. However, most likely this is a physical defect and the unit needs to be replaced. Link to comment Share on other sites More sharing options...
Leam Posted January 7 Share Posted January 7 I just had this issue, but it was because the wide pump cable wasn't fully seated. Fixed that, and now the cool pump lights come on. 🙂 Link to comment Share on other sites More sharing options...
